The Ramzi Theory Explained

The Basics of The Ramzi Theory

“Ramzi’s method is using placenta/chorionic villi location as a marker for fetal gender detection at 6 weeks gestation was found to be highly reliable. This method correctly predicts the fetus gender in 97.2% of males and 97.5% of females early in the first trimester.”

The Gender Experts encourage anyone who is interested in this gender determination theory to research the official study. It is a great starting point to understand the origins of this theory.

How to read your ultrasound scan to determine gender

Our first tip is the most important in reading your ultrasound scan.

1. Ask your technician at your appointment which side your placenta is on.

Dr. Ramzi's study followed strict guidelines and used a control group to achieve the results. They used color flow doppler to view the direction to pinpoint the chorionic villi location. Asking your technician to use this technology will produce the most accurate results. If they reveal that your chorionic villi/future placenta is on the left side of your body, you are likely having a girl; if they reveal it is on the right side of your body, it is likely a boy!

2. Look for the bright area around the sac.

This is likely where the placenta is going to start growing. We have found that some scans are easier to detect the placenta than others. Some scans will show multiple hyperechoic areas of brightness, so if you are unsure, we can help!

3. Are transabdominal scans a mirror image, and transvaginal ultrasound scans true to the same side?

The Great Debate in the Ramzi world is whether transvaginal ultrasounds appear to be on the "same side" as pictured on the scan, and abdominal scans are "flipped," or a "mirror image." Although this is sometimes true, our rule at The Gender Experts is not all scans are created equal.

If we followed this exact method to determine which side the placenta is on, our accuracy rate would not be as high as it is now. Are some ultrasounds on the same side, and others flipped? Yes. However, it does not always have to do with whether it is an abdominal or transvaginal scan. We look for many variables, including annotations on the scan, the anatomy surrounding the sac, the shape of the sac to determine orientation, and more to provide our most educated prediction. Another example of variability when reading scans for Ramzi Theory: In some cases, the scan needs to be rotated 90, or even 180 degrees to be in the correct orientation.


4. Sagittal scans cannot provide insight into whether placenta is located on left or right of the uterus.

What is a sagittal scan?

In the simplest terms, it is a view that appears to slice from left to right. Imagine looking from the right side of your belly and looking in. All you would be able to see is what is up and down, front and back; not left nor right. It is a “long view,” therefore, the only placenta location determination that is possible in this view is whether your placenta is anterior or posterior (toward the front, or toward the back.)

Ultrasound scan must be in transverse view for Ramzi Method determination

Ramzi Theory scans must be in the transverse plane in order to accurately determine which side the future placenta is on. The transverse plane is like looking from your belly button, in. This allows you to see which side is left, and which side is right.

Does it matter which side I ovulated from or which side the baby is on for the Ramzi Theory?

The Ramzi Method can be confusing. Some people will look at an ultrasound scan, and assume it is a boy if the baby is on the right side of the body. However, it is important not to focus on where the baby is, but where the placenta will be forming. Babies do stay close to their placenta in the beginning, but it’s important to remember to look for the bright area first and foremost when trying to determine an accurate Ramzi Theory prediction.

It also does not matter which side you ovulated from. A woman can release from her left ovary, and the baby can implant on the right side of her body just as easily as implanting on the left side.

Further evidence of this is that there are many women who only have one functioning ovary, and they are just as likely to produce a male or a female, regardless of which ovary it is being released from. There is no correlation from ovulation side for determining which side the placenta will form on.

This is a confirmed internal boy scan at 8 weeks gestation. Notice baby is sitting right in the middle. However, the Ramzi Theory states it is not where the baby is, but where the placenta is. The placenta (technically chorionic villi at this stage, as true placenta has not developed yet), is on the left side of the picture, right side of the body.

Other clues to help make a gender prediction is location of the yolk sac, since it normally attaches close to chorionic villi. You can see this on the scan example as leaning toward the left side of pic(right side of body). Further evidence to indicate male fetus is the decidual reaction noted on the scan, which is also on the right side of the body. This can sometimes be seen as a “wall” that surrounds the sac. It is a thickening of the endometrium seen in early pregnancy and a double decidual sac sign is one of the first signs that a pregnancy has occurred.
